Self Air Aspiration Mechanical Flotation Equipment for Gypsum

Summary

Self air aspiration mechanical flotation machine is applicable for the mining of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.

Self suction type mechanical agitation flotation cell for mining belong to inflatable flotation machine. With the ability of imbibing ore pulp, mechanical agitation flotation cell is used as ore pulp imbibing tank.

Working principle

Self aspirated flotation machine in the process of working through rotary motor to drive the

impeller, the impeller in the process of rotation on the one hand, due to the pulp in the center of the impeller was thrown, form a negative pressure here, outside air through the breathing tube into the pulp inside, the impeller under the joint action with the pulp was cut into appropriate size of the bubble, and evenly dispersed in the slurry. On the other hand, through the rotation of the impeller of slurry mineral grains to keep state of suspension, and join the flotation tank flotation reagents in mixing get dispersion under the action of the impeller. First, pulp in flotation reagents first adsorbed on the surface of mineral particles, expand the gangue minerals and mineral products, hydrophobic differences between mineral particles and bubbles under agitation impeller high speed movement and collision, larger hydrophobic mineral particles adsorbed on the surface of bubble and emerge as the bubbles rise together, flotation foam formed in the liquid level has a certain thickness of the flotation foam layer, through the secondary enrichment rinse bubble is mixed gangue mineral or less hydrophobic particles, improve the concentrate grade. By analyzing the aspirated flotation mechanism made known, the flotation machine is mainly through the impeller rotating stirring pulp with inhaled air, so the impeller speed is larger, badly worn.

Features

1. Large air-absorption capacity

2. Low energy consumption

3. Less reagents consumption

4. Easy to maintenance and can be designed according to the users.

5. Every cell owns three functions: air absorption, slurry absorption, and floatation separation, and the cells form a floatation separation loop by itself without any auxiliary equipment, and is allocated horizontally, which favors the change of flow.

6. The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurry respectively.
